+// Parameters
+//  pin    : The pin to check for interrupt. Numbering sequence to be followed as initiated using RPI_pinNumbering function.
+//  timeOut: The time (in milliseconds) for which to wait for interrupt. -1 to wait forever.
+//
+// Description
+//  When called, it will wait for an interrupt event to happen on that pin and the program will be stalled. The return value is -1 if an error occurred (and errno will be set appropriately), 0 if it timed out, or 1 on a successful interrupt event.
+//
+//  Before using RPI_waitForInterrupt, first initialise the GPIO pin and at present the only way to do this is to use the gpio program, either in a script, or using the system() call from inside the program.
+//  Eg: To wait for a falling-edge interrupt on GPIO pin 0, setup the hardware using (before running the program):

+function RPI_sn3218Setup(pinBase)
+// Function for setting up SN3218 I2C based LED controller.

+// Calling Sequence
+//  RPI_sn3218Setup(pinBase)
+//
+// Parameters
+//  pinBase: any number above 64. The consecutive 18 pins will be allocated alongwith.
+//
+// Description
+//  This function sets up the extension module for the SN3218 I2C based LED controller.There is no I2C device address passed into the setup function – the SN3218 has a fixed I2C address of 0x54, so there’s no need to refer to it other than internally inside the driver. This also means that only one device can be connected to a Raspberry Pi.

-//
-// Parameters
-//		pin: pin no on which pwm value is to be changed. Currently only 12 is allowed
-//		value: pwm value for given pin. This must be less than range value set 
-// Description
-//		This function changes pwm duty on specified pin. As for RPi, only one pin 
-//		(pin 12) is available for hardware PWM. 
-//		PWM frequency = (PWM Clock frequency/Clock divisor/range) 
-//				PWM clock frequency = 19.2 MHz
-//				clock divisor is setup using RPI_HardPWMSetClock
-//				range is setup using RPI_HardPWMSetRange 
-//		Actual PWM duty = value/range
-// Examples
